Ok my feedback to the clip.

You can add some turbulence noise to the clouds aka The paramount logo style..

Considering the awesome light behavior you put there i suggest when the falcon start passing the sun the shadow area is more dark.. as the exposure changes suddenly..

To eliminate some flatness of the matte(its fine as it is just saying) you can show some ships landing on the hangar section of the city. the overlaps will give something more..

Maybe some foreground clouds.

I know its wip:) I say what i see
